Hi there, hmfarm.

Let me share some information about importing transactions from your Square app into QuickBooks Online (QBO).

Square is a third party application that can be sync with QBO. The information we receive depends upon them what the Square allows.

To make sure you'll be guided to the right support. It'd be best if you can contact their technical support directly. They have the necessary tools to investigate why some of your Square transactions are not importing or missing.

Don't forget to leave me a reply if you have questions about importing Square transactions in QBO. I'd be glad to assist you further.
